Biological Sequence Databases on the HPC
Some of the most common biological sequence databases are available on the HPC for you to use with tools like BLAST. Below you can find the list of them, their location on the system, and the last time they were updated.
We endeavor to keep this list updated as the One True List™.
|NCBI nr/nt nucleotide collection||2018-11-24||
|NCBI nr/nt protein collection||2018-08-16||
|UniProt's UniProtKB/Swiss-Prot||Manually curated, most reliable||?||
|UniProt's UniProtKB/TrEMBL||Automated curation||?||
Using These Databases
To use these databases you generally need to set an environment variable pointing to the location of the database before running your program. For example, to use
nt with NCBI
$ export BLASTDB=/export/data/bio/ncbi/blast/db $ blastn -db nt -query file.seq -out blast.out
¹ Use the following to determine the date of a BLAST database:
/export/apps/blast/2.7.1+/bin/blastdbcmd -info -db nt | grep Date
